can a map senser be faulty with out putting out a code also cam belt done £76 for belt and £30 to fit it & good it it better and quieterbut still this prob with it hunting every now and again next weeks job

id expect MAP to throw a fault if it was dickie... you done the obligatory throttle clean, throttle relearn and map relearn??

we'll start with the easy things first but dont expect it not to be the timing out slightly.

i well do the map relern tomorrow have done the throttle if not that i think the might be a problem with it will a throttle pedol of any stilo fit

i would assume so but i dont know for certain...

what makes you think its the pedal?

when i got the car last year it had a second hand engineput in it and the car it self had done 135000 miles so i thought maybe its a bit worn out coz all of the running was ive put all new running gear on itengine is in good con so i thought it could only be one of two things in my mind throttle pedol or houseing what do you think i am going to try to get it over to shadey if i can this week seeif he can put it on is computer

I think that MAP sensor after years of exploatation can get a sort of "bias", and it would not give exact pressure measurements. I beleive that is happening with my car, but it's not making troubles. To be sure, it can be checked with vacuum pressure gauge, but this also has it's price. If it doesn't throw any codes it is obviously within the range of "good work".

For the pedal, you can check it's output. Also, you can check throttle body signal output, as this is common problem for 1.6.

can you tel me how you do these checks or is it worth it just changing the map for a new one

If you have Fiat ecuscan you can look with it. Also there are few posts about it from Deckchair5.

thanks will have a look
